Dec 10, 2017 · Zinc, which comprises the hot-dip galvanized coating is very high on the Galvanic Series (right), which means it will be anodic to most other metals. So, when hot-dip galvanizing is connected to other metals, the zinc coating will not only sacrifice itself to protect the underlying base steel, but also try to protect the other connected metals.
Galvanized Iron Sheet - HarwalShop - Shop OnlineThe most common method is hot-dip galvanizing, in which parts are submerged in a bath of molten zinc. Galvanized iron (GI) sheets are steel sheets which are basically coated with zinc and include a range of hot dip galvanized and electro-galvanized steel sheets.

Galvanized vs. Galvannealed Steel Sheet. Galvanized steel sheets are continuously hot dipped with a durable protective coating of zinc. This can be formed without flaking or peeling, and the protective qualities cannot be impaired by such actions as stamping, cold
What is Galvanized Steel? - Definition from CorrosionpediaDec 08, 2015 · Galvanized steel has a longer life and durability compared to non-galvanized steel. The application process of zinc on a steel structure is called "galvanization." This process was first invented and developed in France and England in 1837, in which a sheet of steel was dipped in a molten zinc bath (a method called "hot dip galvanization").HOT DIP GALVANIZED - AK SteelHOT DIP GALVANIZED STEEL, known as ZINCGRIP® Steel, is continuously coated on both sides with a zinc coating. The hot dip process, pioneered by AK Steel, provides a tight metallurgical bond between the steel and the coating. This process results in a material with the strength and formability of steel plus the corrosion protection of zinc.
